...this land was recently in litigation, was cleared a few weeks ago after the case reached the California Supreme Court. Last week it looked as though Mrs. Bishop's troubles were over. Newsstories from Southern California made it appear that Mrs. Josie Bishop owns an extremely rich deposit of radium-bearing ore-one of the richest, in proportion of radium to the ton, ever discovered...
...rich radium deposit is one which yields 90 to 120 milligrams (.00315 to .0042 oz.) nearly pure radium bromide salt per ton of concentrated ore (50 tons of crude ore). From ore bodies of such richness in northwestern Canada the refining plant is able to extract one gram of commercially pure radium from 550 tons of mined ore. A San Diego mining engineer and chemist named F. S. Kearney, now working in Mexico, assayed Mrs. Bishop's ore at 130 milligrams of radium per ton. This high figure, Mrs. Bishop said, was confirmed when she sent a sample...
...across the frozen surface of Canada's Great Bear Lake, which is cut by the Arctic Circle. He spotted a vein of curious, glossy stuff which looked something like anthracite coal, with gleams of yellow, pink and green, recognized it as pitchblende. Surveys and assays showed that the deposit was rich and copious. In 1933 a refining plant was completed at Port Hope on Lake Ontario, 3,500 miles away. The Great Bear Lake find broke the Belgian monopoly, reduced the price of radium to its present level of $25,000 per gram. Few months ago Canada celebrated production...
...Founder in 1928 of National Statistical Service, Inc., Mr. Schwarzschild still supervises the annual publication of famed, authoritative American Underwriting Houses and Their Issues. Believing that the obsolete security business begun by Mr. Smythe needs to get beyond Wall Street and the Produce Exchange into the attics and safe-deposit boxes throughout the East, Mr. Schwarzschild last week announced a campaign to arouse owners of forgotten bonds. This week Smythe, Inc.'s first traveling library will leave Manhattan in a trailer for upstate New York in charge of two young men commissioned to set up as consultants...
Entomologist Orlando S. Bare of Nebraska Agricultural College last week warned farmers in his State not to relax their poison campaign, or they would suffer a double penalty: continued heavy damage to this year's corn crop, and a heavy deposit of eggs to menace next year's. Most of the 462 carloads of Federal poison shipped in had been used up, however, and many farmers in desperation were paying from their own pockets for bait bought from private dealers. In Colorado, an anti-grasshopper council was organized by the State agriculture extension director. In Arizona, a State...
